[BlindMath] Accessibility of these Technologies

Hello Nicholas,

There are 3 types of technology I'm seeing here:

1.       Data APIs like TMDb API and Databricks

2.       Server technology, such as Flask, SQL and Amazon Web Services

3.       Data Visualization tools, such as D3 and Tableau

For the most part, 1 and 2 are accessible over the command line, or can be
easily accomplished in other ways.

For 3, you're going to need help, there is no good way to make custom
visualizations without seeing the data. I would ask if you can Sonify the
data instead, it's a way of representation that's way more accessible to


Here are my experiences with the technology:

5. Learning to use D3 visualization library

You can do it, but it's coding, and there's no way to check your output. If
you have Aira or Be My Eyes, you can call them every time you change the
code and ask them what they see, but it's very annoying. I always hire a
sighted person to do my D3 work. I have managed to code some
visualizations, but it's not fun. If you have a Graphiti, you may be able
to touch the output, but I've never tried it.



Is the best tool for doing visual graphs and charts nonvisually.

7. Flask

It's a server, so you can use it from the commandline

8. Tableau

I would ask to use SAS:


It's a competitor that's much more accessible. Contact:

Ed Summers Ed.Summers at sas.com

For questions, problems, or bugs.

11. Amazon Web Services


12. Google Cloud Platform

You can use on the command line, and the web interface is pretty good.

If you have a data to perception class, or a data representation class, it
may be more accepting of alternative representation methods. If the class
is just data visualization, it's going to be brutal, like a deaf person
taking an ear training music class.

There are blind professionals in data representation, but they use sound
and touch, which IMO each have as many possibilities as data visualization,
and each have extensive research behind them.

Talk to the teacher and ask about Sonification and send them the
Sonification handbook.
